Molycorp (MCP) announces discovery of heavy rare earth deposit

Founder and Editor,

I know I just finished a big post on rare earths but this news from Molycorp (MCP) arrived too late to get into that post

Molycorp has filed a form 8K with the Securities and Exchange Commission with a Regulation FD Disclosure announcing that today, October 4, the company will announce at an industry conference that it has discovered a heavy rare earth deposit on mining claims it owns near its Mountain Pass, California, mine.

This is a big deal—even with the company’s disclosure that it still has to do lots of test drilling to determine the quantity and quality of the deposit.

A story in this morning’s New York Times fills in some of the details.

The discovery is actually a rediscovery of a find that dates back to 1950. In the 1980s the oil companies that owned the mine, Unocal and then Chevron (CVX), were interested in light rare earths used in oil refining and color TV screens and the discovery of a deposit of heavy rare earths was buried in the files. Global demand and pricing have shifted since then so now it’s heavy rare earths, such as dysprosium and terbium, which are in short supply and command the highest prices.

The heavy rare earth deposit, Molycorp CEO Mark Smith told the Times is on land near the existing mine and where Molycorp already has claims and permits. That, plus the situation of the deposit relatively near the surface requiring very little strip mining, might allow the company to begin producing heavy rare form the deposit in a little more than a year.

The company’s new rare earth refinery, set to open in stages at the Mountain Pass site between the end of 20112 and 2014 can process either light or heavy rate earths.

A heavy rare earth discovery has the potential to make a major difference in Molycorp’s profitability. Take dysprosium, one of the 10 heavy rare earth elements. Total annual global production came to just 100 metric tons, so we’re talking rare, rare earth here. At the beginning of September dysprosium oxide sold for about $2,270 a kilogram. A light and more common rare earth such as lanthanum oxide sold for about $140 a kilogram.

Since we don’t know how big this deposit might be or what the concentration of heavy rare earths might be it’s impossible to tell how much this rediscovery changes Molycorp’s bottom line. But I liked this stock before the announcement and I certainly don’t like it less now.

I’m bullish on Molycorp but since I’m bearish on the market as a whole I don’t see a reason to chase this stock today. (It’s up 1% as of 2:30 p.m. New York time.) Certainly a $30 price is reasonable for this stock, but with the trend in the market pointing downward you will be able to get this more cheaply, in my opinion. If you want to hedge your bets you can, of course, dollar cost average down by beginning a small position now and adding to it as the months go by (or the stock prices sinks.) At the moment (October 4), though, I’m going to add this stock to my watch list
